TECHNICAL FIELD OF THE INVENTION
The invention relates to a railway vehicle, and in particular one funicular, in particular for transporting heavy loads, such as by example containment hoods for radioactive waste intended to be buried in a website underground.
PRIOR ART

[0002] In the document FR 2 954 747 is described a funicular intended to transportation of radioactive waste between a surface top station and a station downstream from an underground landfill. An inclined ramp connects the top station to the downstream station and materializes a railway line and one or more ways of counterweight. A trolley is traveling on the transport track while one or various counterweights travel in the opposite direction on the counterweight track. Carriage and the counterweights are connected by two cables which each pass through a pulley motor, to provide the installation with redundancy in order to increase its safety. the frame metal of the carriage rests on running rollers, four in number to less, and preferably eight. These rollers can be mounted on a suspension steep primary, for example by Belleville washers. To take into account them possible slight variations in the spacing of the rails, the rollers rolling on one of the rails can be with guide cheeks, while rollers on the other track can be cylindrical. This suspension, although intended for transport of heavy loads, is not suitable for the conditions of use, and does not not guarantee a balanced distribution of the load between the rollers.

[0003] In the document CH415731 is described a vehicle intended to circulate on a railway track, and comprising a frame defining a plane vertical median longitudinal. The chassis rests on at least a first train of rolling at rockers, comprising two independent side rocker devices located from either side of the median longitudinal vertical plane. Each device of pendulums side comprises: a secondary balance articulated with respect to the chassis around a horizontal secondary pivot axis, and two primary balance wheels, each of the two primary balances being hinged with respect to the balance secondary about a horizontal primary pivot axis, the pivot axes primary of the two primary pendulums being distant from each other, longitudinally on either side and on the other side of the secondary pivot axis, each primary balance wheel being associated at least two carrying rollers intended to roll on the railway track of traffic, each rotating around an axis of rotation parallel to the axis of pivoting primary of the associated primary balance beam, and located longitudinally on either side of the axis primary pivoting of the associated primary balance beam. However, this vehicle is not not suitable for driving on an inclined lane. Furthermore, none arrangement particular is taken for the loading and unloading of the vehicle, nor for its braking, nor for its traction.

[0004] The invention aims to remedy the drawbacks of the state of the technical and to propose a vehicle running on the railway, and capable of transporting of the heavy loads by balancing the load on the track.

[0005] To do this, it is proposed, according to a first aspect of the invention, a cable traction vehicle intended to travel on a railway track traffic, and comprising a frame defining a median longitudinal vertical plane and at the less a first deflection pulley for guiding a traction cable pulling the vehicle in a first predetermined direction of traction, the first deflection pulley having an axe of rotation located in the median longitudinal plane, and rotating in a bearing attached to the vehicle chassis. The chassis rests on at least a first train bearing with pendulums, comprising two lateral pendulum devices independent located on either side of the median longitudinal vertical plane.
Each lateral balancer device comprises: an articulated secondary balancer by relative to the chassis about a horizontal secondary pivot axis, and of them primary balance wheels, each of the two primary balance wheels being articulated by report to the secondary balance around a horizontal primary pivot axis, the axes of primary pivoting of the two primary balance wheels being distant Fun from the other, longitudinally on either side of the secondary pivot axis, each primary balance being associated with at least two carrier rollers intended to roll on the circulation railway, each rotating around an axis of rotation parallel to the primary pivot axis of the associated primary balance beam, and located longitudinally on either side of the primary pivot axis of the balance associated primary.

[0006] The arrangement of the primary and secondary pendulums of each device of lateral rockers makes it possible to balance the forces exerted on the rollers carriers, and therefore a distribution of the weight of the vehicle over a large number of rollers carriers.

[0007] According to a preferred embodiment, the vehicle is intended to one low-speed traffic on a straight railway track whose condition is mastered and control. There is therefore no need to allow a pivoting of the train of bearing or lateral pendulum devices around an axis of spin perpendicular to the track. The secondary balance wheels are articulated at the frame of such so that the secondary pivot axes of the secondary pendulums are always perpendicular to the median longitudinal vertical plane. There is therefore no no rotation of the secondary balance wheels around a second axis perpendicular to their secondary pivot axis. Each secondary joint is therefore a connection pivot to one pivot axis only.

[0008] Preferably, the primary pendulums are articulated by compared to secondary pendulums so that for each device of pendulums side, the primary pivot axes are always parallel to the pivot axis secondary. Articulations are therefore pivotal connections to an axis of pivoting unique.

[0009] According to one embodiment, each balance device side comprises a plate connected to the frame and to which the secondary balance is Speak clearly. Preferably, and for each side rocker device, the platinum is connected to the frame by means of one or more jacks oriented perpendicular to the secondary pivot axis. Preferably, the jacks are able to lift the chassis to set the vehicle in motion and to lower the chassis for loading or unloading phases or for braking emergency. The vehicle may include skids attached to the chassis, intended to come in bearing against a brake track running alongside the railway track when the chassis is lowered.

[0013] According to a preferred embodiment, the vehicle comprises at minus one second deflection pulley to guide a traction cable (which may or may not be identical to the traction cable passing through the first return pulley), said cable tractor pulling the vehicle in a second direction of traction opposite to the first sense of traction, the second deflection pulley having an axis of rotation located in the plan median longitudinal, and rotating in at least one bearing secured to the frame from vehicle and preferably offset longitudinally with respect to the bearing of the first return pulley in the second direction of traction. This provision also contributes to a good orientation of the vehicle on the railroad of traffic.

[0014] Preferably, the unladen center of gravity of the vehicle is located in the first direction of traction, at a distance and behind the landing of the first pulley reference, in the median longitudinal plane of the vehicle. This provision contributes also, on a straight inclined traffic lane, at a good direction of vehicle on the railway track.

[0015]
In practice, the vehicle comprises at least a second train of pendulum bearing, remote from the first pendulum running gear in a longitudinal direction of the vehicle. The second running gear at pendulums is similar to the first pendulum undercarriage, and has two devices independent lateral rockers located on either side of the vertical plane median longitudinal.

[0016]
The unladen center of gravity of the vehicle is preferably in between the secondary pivot axes of the two pendulum undercarriages. In the hypothesis of a platform supporting a load, the latter is disposed preference between the secondary pivot axes of the two sets of rolling at balance beams so that the loaded center of gravity of the vehicle is also located between the secondary pivot axes of the two undercarriages.

[0017] According to one embodiment, the vehicle is driven by cables, and is not motorized. In particular, the carrying rollers of the first train of rolling at rockers and of the second rocker running gear are not motorized.

DETAILED DESCRIPTION OF EMBODIMENTS

In Figure 1 is illustrated schematically and simplified one funicular comprising a top station 10, a bottom station 12 and a circulation 14, preferably rail, on which circulates back and forth a vehicle single 16 intended to carry a load either from the top station 10 to the bottom station 12 or from the bottom station 12 to the top station 10. The track traffic 14 preferably has a constant inclination between the top station 10 and the station downstream 12.

[0025] The top station 10 is equipped with two drive pulleys 20.1, 20.2, driven by motor means 22.1, 22.2, which may be common or independent for each pulley.

[0026] The downstream station 12 is also equipped with two pulleys 24.1, 24.2, free in rotation, and rotating around axes parallel to those of the driving pulleys from the station upstream 10.

[0027] The vehicle 16 is itself equipped with two return pulleys 26, 28 of large diameter, rotating freely around two axes A, B located in a plan median longitudinal median P of the vehicle 16. The return pulleys 26, 28 are arranged at a distance from each other along the path of the vehicle, one side from the top station 10, and the other on the side of the bottom station 12.

[0028] A closed-loop cable 30 is pulled between the pulleys of footnote 26, 28 of vehicle 16 and the pulleys 20.1, 20.2, 24.1, 24.2 of the top and bottom stations.
More specifically, the cable 30 comprises a first tractor section 32.1 drawn enter here upstream return pulley 26 of the vehicle 16 and a first (20.1) of the pulleys of the top station 10, a first connecting section 34.1 drawn between the first pulley motor 20.1 and a first of the pulleys of the downstream station 24.1, a first section return 36.1 pulled between the first pulley of the downstream station 24.1 and the pulley downstream return 28 located on the vehicle 16, a second return section 36.2 drawn between the downstream return pulley 28 and the second downstream station pulley 24.2, a second connecting section 34.2 pulled between the second downstream station pulley 24.2 located at the bottom station and the second driving pulley 20.2 of the top station 10 and one second tractor section 32.2 between the second driving pulley 20.2 and the pulley upstream reference 26 of the vehicle 16, thus closing the loop.

[0029] Optionally, each of the two connecting sections 34.1, 34.2 passes through a tensioning device 38.1, 38.2 comprising a pulley of upstream guide 40.1, 40.2, a downstream guide pulley 42.1, 42.2 and a pulley mobile 44.1, 44.2 supporting a weight 46.1, 46.2 moving in a well vertical 48.1, 48.2. In the schematic representation of Figure 1, the orientations spatial of the pulleys and the path of the cable have not necessarily been respected, but they will come out better from figures 2 to 10.

[0030] Cable braking devices are also provided 49.1, 49.2, which can for example act on the driving pulleys 20.1, 20.2., or on the sections of 32.1, 32. cable tractors.

The vehicle 16, illustrated in detail in Figures 2 to 5, has a chassis 50 on which is formed a horizontal platform 52 supporting the load 54. We can define a longitudinal axis X of the vehicle parallel to the direction of the path rectilinear, a transverse axis Y, perpendicular to the previous one and horizontal, and one third reference axis Z of the vehicle, perpendicular to the previous ones and to the way traffic. The frame 50 rests on an upstream undercarriage 56 and a train downstream running gear 58. Each running gear is made up of two devices independent 60 side rockers. Each pendulum device side 60 comprises a secondary pendulum 62 pivotally mounted about an axis 62.1 on a plate 64 fixed to the frame by means of two jacks 66, and two pendulums primary 68 articulated with respect to the secondary balance 62 around axes of pivoting 68.1, and on each of which are mounted two carrier rollers 70 rolling on taxiway 14, and rotating around axes 70.1. Cylinders 66, which are oriented along Faxe Z perpendicular to taxiway 14, do not have a filtering suspension function, but allow the chassis to be lifted 50 above from the ground to set it in motion and to lower it in contact with the ground of the track 14 to stopping for the loading or unloading phases at the station, or in movement for emergency braking. The pivot axes 68.1 of the balances primaries 68 are arranged longitudinally on either side of the pivot axis secondary 62.1, and the axes of rotation 70.1 longitudinally on either side of the axes of primary pivoting 68.1, which allows a balancing of the forces exerted by the carrying rollers 70 on the track. On one side of the vehicle, the rollers 70 are cylindrical, while on the other, they are provided with side guide flanges 70.2, to allow compensation for any slight variations in the gauge of the rails.
Each roller 70 can also be provided with a brake 70.3.

[0032] Figures 2 to 4 show the positioning of the two pulleys return 26, 28 of large diameter, on the chassis, above the track of traffic, and rotating around two axes A, B located in the longitudinal median plane, and slightly inclined in relation to Faxe Z perpendicular to the lane of traffic. The return pulleys are guided relative to the frame 50 by bearings 26.1, 28.1.
located at a fun distance from each other along the path of the vehicle. In the occurrence, the bearings 26.1 of the upstream return pulley 26 connecting the vehicle to the top station is located upstream of the bearings 28.1 of the downstream return pulley 28 connecting the vehicle at the base station 12. In addition, landings 26.1, 28.1 are located longitudinally between the secondary pivot axes 62.1 of the upstream undercarriages 56 and downstream 58. Guide rollers 72 are arranged along the track to support the cable 30. The return pulleys 26, 28 are arranged above the rollers of guidance 72. The frame 50 is equipped with orientation rollers 74 which allow the cable 30 to be lifted and oriented in the oblique plane of the return pulleys 26, 28.

[0033] The vehicle can also be equipped with driving positions 76 upstream and downstream each provided with a control panel 78. The chassis 50 of the vehicle has wear pads 80 which, when the cylinders 66 are in position low, rest on the ground.

[0034] Figures 6 to 8 show the path of the cable in the trainstation upstream. The first tractor section 32.1 enters the station following a trajectory lying essentially in a vertical plane parallel to the X axis of the trajectory from the return pulley 26 to the driving pulley 20.1. He going away even of the second tractor section 32.2 between the return pulley 26 and the second driving pulley 20.2. Leaving the first driving pulley 20.1, the first section connecting cable 34.1 crosses the two tractor sections 32.1 and 32.2 and is diverted by the upstream guide pulley 40.1 towards the mobile pulley 44.1 in the well 46.1 to emerge and be guided by the downstream guide pulley 42.1 in order to walk in a vertical plane parallel to the trajectory of the vehicle 16, up to the downstream station 12. The second connecting section 34.2 follows a trajectory similar in crossing the two tractor sections 32.1, 32.2 and being diverted by the pulley upstream guide 40.2 to the mobile pulley 44.2 in the well 46.2 for come out and be guided by the downstream guide pulley 42.2 in order to travel in a plane vertical parallel to the trajectory of the vehicle 16, as far as the downstream station 12.
the crossing of the connecting sections 34.1 34.2 with the tractor sections 32.1, 32.2 in the top station 10 makes it possible to ensure contact between the cable 30 and each of driving pulleys 20.1, 20.2 on more than 180, and in practice on more than 225, and of preference out of more than 240 . In this embodiment, the pulleys of guidance upstream, the downstream guide pulleys and the mobile pulleys have axes of spin horizontal, while the drive pulleys have vertical axes.

[0035] Figures 9 and 10 illustrate the downstream station 12 equipped with two pulleys 24.1, 24.2, free in rotation, and rotating around axes vertical. The diameters of the motor pulleys 20.1, 20.2 of the top station and pulleys crazy 24.1, 24.2 of the bottom station are preferably substantially identical. As illustrated in Figures 2 to 10, the connecting sections 34.1, 34.2, in their path along track 14, surround the tractor sections 32.1, 32.2 and the sections of back 36.1, 36.2.

[0036] The symmetry of the installation is such that in theory if the two pulleys motors 20.1, 20.2 are driven at equal speed in directions opposite, and assuming the dynamic elastic deformations of the cable identical to leave and on the other hand, the vehicle 16 is driven in the uphill or downhill direction.
descent, without that the return pulleys 26, 28 rotate. In practice, the conditions of one perfect symmetry are not achieved, for example due to differences of perimeter of the driving pulleys, and the rotation of the return pulleys 26, 28 allows a dynamic balancing of the forces exerted on the sections of the cable 30.
may also choose to control the driving pulleys 20.1, 20.2 with a difference of speed, so as to cause permanent rotation of the return pulleys 26, 28, as previously discussed. This speed difference can be constant or variable, especially periodically.

[0037] It is also noted that the relative positioning of the bearings 26.1, 28.1 allows in the event of a slight misalignment of the vehicle with respect to the track, of generate a return torque on the chassis 50 of the vehicle, which brings the vehicle in alignment. The positioning of bearings 26.1 upstream of the center of gravity of the empty vehicle and upstream of the platform 52 supporting the load 54 allow also to ensure correct orientation of the vehicle on the lane, both empty what about load, insofar as the center of gravity of the unladen vehicle 16 is in the plan median longitudinal, and that the load 54 is also positioned so at this that its center of gravity is in the median longitudinal plane.

[0038] In the event of failure of one of the motors 22.1, 22.2, it is possible to actuate the corresponding brake 49.1, 49.2 and driving the vehicle 16 at reduced speed with the other engine.

A second embodiment of the invention is illustrated by way simplified and schematic in Figures 11 and 12. According to this mode of achievement, the hauling cable 30 is a closed loop cable having a first section tractor 32.1 between a return pulley 26 on the vehicle 16 and a first pulley motor 20.1 located in the upstream station, a first connecting section 134.1 drawn Between the first drive pulley 20.1 and a second return pulley 26 mounted on a counterweight 140 circulating on a counterweight track 140 parallel to the track of circulation 14 (preferably below the latter), in the opposite direction from vehicle 16, a second connecting section 134.2 drawn between the pulley of counterweight 124 and a second drive pulley 20.2 located in the upstream station, and a second tractor section 32.2 pulled between the second drive pulley 20.2 and the pulley of reference 22, closing the loop of the cable 30. To facilitate the understanding of the entire funicular, the spatial positioning of the various elements of the installation is not voluntarily not in conformity with reality.

[0040] To control the funicular according to the invention in its different modes of realization, different sensors can be used to measure different installation status variables, and in particular: speed sensors or of rotation drive pulleys 20.1, 20.2, speed or rotation sensors of the pulleys 24.1, 24.2 of the bottom station, speed or rotation sensors of the pulleys reference 26, 28, extensometric sensors detecting the elongation of the different sections of the cable or some of them, force sensors resulting on the axis of the upstream return pulley 26, of the vehicle speed sensors 16, motor torque sensors of the driving pulleys 20.1, 20.2.

Naturally, various modifications are possible. We can notably double the installation, so as to ensure redundancy in traction.

[0042] The power-up devices are not necessarily placed on the tractor sections, but can be done alternatively on the sections link or return sections. Drive motors can be arranged in the downstream station. It is also possible to envisage a motorization distributed between the of them stations.
